Struct DiscoverRequest 

pub struct DiscoverRequest {
    pub method: String,
    pub params: RequestParams,
}

Core MCP protocol types and error handling Client → server server/discover request.

DiscoverRequest extends JSONRPCRequest { method: "server/discover", params: RequestParams }.

The jsonrpc: "2.0" and id fields are supplied by the JsonRpcRequest envelope when this typed payload is wrapped for the wire — matches existing crate convention (CallToolRequest, ListToolsRequest, etc.).

Fields
